So here's another update: I've greatly improved the efficiency of the program and have got it working 80% of the time. The other 20% an endless loop occurs. Since this is based on probability, it is likely that my end condition simply isn't met for a very long time, making it appear like an endless loop but not this often. Whatever advice you guys have would be great!
